T 0 all whom it may concern:

Be it known that l, SAMUEL S. Rose, a citizen of the United States, residing at Santa Clara, county of Santa Clara, State of Caliprovementsin Gearing, of which the followmg is a specification.

My invention relates to improvements in gearin The object of my invention is to provide improved gearing, whereby a shaft may be and without any tendency in the mechanism to bind during its operation My invention consists in the novel arrangement and combination of parts described in the following specification and shown in the accompanying drawing, and as claimed in the appended claims, and I declare that my invention as set forth in this specification and illustrated in said drawing is so described that any person skilled in the art to which it pertains may make and use the same.

Referring to the accompanying drawings: Figure 1 is a plan view of my said device; Fig. 2 is a sectional view of the same; Fig. 3 is a section of said device on line yy of Fig. 2, and Fig. 4 is a section of the same on line a:ac of said Fig. 2. Fig. 5 shows four parts that form the collar 12, each section of said collar as shown being composed oftwo parts, having lugs 28 containing apertures by means of which the parts are connected by bolts and nuts. Fig. 6 shows the parts last mentioned as assembledupon sleeve 20 etc cepting one part out of contact with the other parts. Fig. 7 is a sectional view of the said four parts forming the two sections or the collar 12 joined upon the sleeve 20.

The following is a description of the parts of my'device as shown in said drawing and its mode of operation.

A- represents a driving shaft havinga pinion 2 operating two oppositely positioned gears 3 and 4. Said gears are loosely mounted on shaft 5 between collars 6 and 7 secured to said shaft. The shaft 5 is driven in either direction by operating a lever 8 which is fulcrumed at 9 and at the upper end of said lever a pin 10 engages a groove 11 in collar 12, and at its other end said lever is connected to controlling lever 13, by the lateral movement of which lever 8 is moved.

The arms 14 are pivoted to collar 12 at l point 15 and at 16 to frictional shoes 17. The said shoes are fulcrumed at 18 to arms 19 which are integral with sleeve 20. When. said collar 12 is caused to operate in one direction the friction from shoes 17 as opci'at ing aga'inst the circular interior of gear 1 causes said gear to revolve and, the sleeve 20 being keyed to shalt 5 thereby causes said shalt to turn in the same direction as said gear. The arms 21 are similarly pivoted. to collar 12 by pintle 22,-and by pintle 23 to vtrictional shoes 24. The said shoes 24 are l'ulcrumed at .25 to arms 26 which are lihcwise integral with sleeve 20. When the collar l2 caused to operate in the direction opposite to that hcrcinlnnore mentioned the friction from shoes 24 as operating against the circular interior cl said gear 3 causes said gear to revolve, and the sleeve 20 being keyed to shalt 5, ashorcinhetore set forth, thereby causes such shaft to turn'in the direction opposite to that turned by gear -t.

The collar 12 consists ol two sections so as to allow either section to move a small distance to prevent binding, when either of the frictional shoes swing on an are caused by the pivoting ol" the same as shown at points 18 and 25. Each section can revolve independently of the other by the annular llange of one section turning in the groove oi the other section, as shown at point 27, such turning being accomplished without liability to bind.

l have described thelcver o as shown in Fig. l, but said lever has'its upper part U-shapcd, the part opposite to that shown in said iignre being identical with the part so shown, including the pin.

it is to be understood that while I have illustrated and described the referred embod iment. oi mv invention, reserve the rightto make all changes which properly fall within its spirit and scope.

Having thus described my invention what I claim as new and desire to secure-by Letters Patent, is:

, groove in the other section and said collar having central annular groove, a lever and pins for shifting said collar and means for securing said shoes to said shaft, substantially as described.

2. Gearing, comprising a air of loosely mounted gears, a driving emit, a pinion thereon meshingwith said gears, pivotally mounted shoes for hearing against the circular interior of said gears, a shaft for said gears, a collarhavingtwo sections mounted between said gears, one of said sections having an annular flange turnable in an end groove in the other section and said collar having a central annular groove, a lever and pins for shifting said collar, a horizontal lever for controlling the last named lever and means for securing said shoes to said shaft, substantially as described Gearing, comprising p of loosely mounted gears, a driving shaft, a pinion 4. Gearing, comprisinga 'air of loosely mounted gears, a driving s aft, a pinion thereon meshing with said gears, pivotally mounted shoes for hearing against the circular interior of said gears, a shaft for said gears, a collar having two sections mounted between said gears, one of said sections having an annular flange turnaole in an end groove in the other section and said collar having a central annular groove, and flanges forming the Walls of said groove a lever' and pins for shifting said collar and means for securing said shoes to said shaft, substan tially described.

5. Gearing, comprising in combination two oppositely positioned gears, a collar consistng of two sections, each of said sections be ing arranged to endwise engage. other section, and a shoe pivotally connected to each of said sections so as to bear against the interior of one of said gears upon the lateral movement of said collar in the direction of said i In testimony whereof l. ailix my signature in presence of two witnesses.
